Comparative Analysis of Residual Stresses in Aluminum Components Produced by Wire Arc Additive Manufacturing (WAAM) and AdditiveFriction Stir Deposition (AFSD)

Javadi, Yashar (Principal Investigator) MacLeod, Charles Norman (Co-investigator) BUFFA, GIANLUCA (Co-investigator) Tamimi, Saeed (Co-investigator) Rahimi, Salaheddin (Co-investigator) Paradowska, Anna (Co-investigator) Alipooramirabad, Houman (Co-investigator)

This collaborative study between ANSTO, University of Palermo, University of Strathclyde, and AFRC investigates residual stresses in aluminum components produced via WAAM and AFSD (including MELD). Using neutron diffraction and ultrasonic techniques, the project aims to characterize and compare stress profiles across processes. The findings will inform process optimization and contribute to a doctoral thesis on in-situ stress measurement in metal additive manufacturing.

KTP 10106664: Knowledge transfer partnership between University of Strathclyde and ETHER NDE LIMITED

Mohseni, Ehsan (Principal Investigator) Dobie, Gordon (Principal Investigator) MacLeod, Charles Norman (Principal Investigator)

ETher NDE has identified a significant potential market for in-process Non-Destructive inspection, of high temperature additive manufacturing.
In most traditional material manufacture, inspection is done on a finished soliditem after manufacture. Whereas in additive manufacture, there is the opportunityfor inspection as the layers are built up. This would be particularly relevant forparts where the core is an open lattice (for reasons of weight reduction), whichmakes conventional non-destructive testing (NDT) at the best very difficult and atworst impossible.
It is imperative that the new product offering is integrated seamlessly with ETherNDE's existing technology where complementary hardware and applicationrequirements align. The innovative proposed product will be designed to work withexisting Eddy Current hardware from ETher's product range. There'll be a PCapplication to facilitate data collection, display, analysis, and reporting.
The metal additive manufacturing market is still emerging, and engagement withAM machine builders has revealed a significant gap in NDT technology. ETherNDE is ready and well-positioned to enter the Eddy Current array market for metalAM in aerospace, and other sectors, with the vision and ambition of overtakingtraditional in-process inspection, thereby helping them gain a technological edgeover their global competitors.

KTP 10106861: Knowledge transfer partnership between University of Strathclyde and NATIONAL OILWELL VARCO UK LIMITED

Mohseni, Ehsan (Principal Investigator) MacLeod, Charles Norman (Principal Investigator) Lines, David (Principal Investigator)

The National Oilwell Varco UK Limited team in Forfar is responsible for the standardisation of non-destructive evaluation (NDE)procedures for our equipment across the globe. Conventional calibration practicedby NOV can be unreliable, as the testing equipment may travel thousands of milesoverseas after the initial calibration. The rigours of the journey could can alter thecharacteristics of the calibration equipment and thus make comparison toequipment in the field unreliable. NOV's oilwell drilling components are oftenmetres in span and extremely heavy, which makes it practically impossible to havestandard reference blocks of the same size as the original equipment. Introducingportable, down-scaled sensitivity pieces for calibration use in the field willtransform the reliability of NDE processes and safety of the components inoperation, minimising the risks of failure and shutdown. The accuracy of amanufactured sensitivity piece is critical: the defects/discontinuities must bereliable and consistent with the piece of equipment targeted for calibration.
Through this KTP, NOV will gain the permanent capacity to design, manufacture,and use sensitivity pieces for in-field inspection of equipment using Phased ArrayUltrasonic Testing (PAUT).
